TAK TAK TAK TAK TAK!!!

[(Yoshi)]

Hey I know there have probably been post about this before and I would usauly search but our dial up has been weird lately and takes for ever to load pages so please excuse me.

Any how I got my car a couple of months and it allways had a tick tick tick noise and I think its the timeing chain but its been constant and quiet so I was hoping I could make it through the winter but today on the way home from school I started hearing a funny noise comming from the engine bay and the close I got the louder I got and when I got home I popped the hood and instead of tick tick tick it was TAK TAK TAK TAK!!! I checked around to make sure nothing was hitting or rubbing and check both fans an both were free. Could it be the timing chain or something else? If this has happened to any one how do I go about fixing it?

Thank you for all your helpAdiosJosh

could be. But it's more likely the valves. Since it's a cam on bucket design, the buckets have to be shimmed as the lobes wear down over time.

Because it is cam on bucket, it would not drastically change pitch like that. Unless the car is extremely low on oil. It usually takes quite a while for the gap to open up using the cam on bucket design. They won't just collapse like hydraulic lifters.

A tapping that rapidly progresses as you have described is usually a rod nock. The speed of the tapping can be a great help in diagnosing these noises as the crank spins twice as fast as the cams. If you are unsure of what you think it is, I would have it towed to a mechanic.

Well, that may be the case but I probably should have said this above, the sound isn't metalic, it sounds like plastic. I don't know if that helps or anything.

Thank youJosh

[nismopu]

it sounds just like a stuck lifter problem i used to have! I ran some marvel through the crank case and drove it a few miles. the sound was gone before i even left the auto parts store parking lot where i poured it in.

[(Yoshi)]

well, its comming from the front of my engine, and I had previousely had fuel injector problems and I used marvel to fix that.

ThanksJosh

take your valve cover off. i had this problem with my ka (and have heard of many people with this problem) see if the TOP timing chain guard has broke. Its a simple piece, but may have caused you to blow your motor (like I did) You might be able to hear it rattling like that when you crank the car up and listen to the valve cover. Its easy to check it, take 5 minutes.

[(Yoshi)]

Ok Ill check. Thanks

Forgive me if this sounds like a dumb question but this is my first car so I havent done this stuff before. Anyhow when I take my valve cover off, do I have to drain my oil or anything. Also if this is the case how much is involved in fixing it?

Thank you for your patients and help.AdiosJosh

[tjmhillz]

no you dont have to drain your oil. i have the same problem right now. a mechanic told me that its one of my valves that is loose. so hopefully that is the problem. do nebody know where i can get stock valves from.

[s14 2510's]

I have a good used head. [email protected] if you want it

[Nismochick240]

tjm-hillz- i might be able to let go of an extra set of stock valves i have. let know an offer

okay after highjacking-- to take off valve cover, just loosing up the bolts around the cover. but do it from opposite ends like this1 3 5 2 4I cant remember how many bolts there are but you get it. and there are also bolts in the middle inbetween the spark plug holes (3 on the s13 and 2 on the s14) if i remember correctly you have to take those off too... dont forget to pull spark plugs wires out good luck!

How is a valve loose?

[(Yoshi)]

Thanks Nismo thats exactly what I needed to know. I just have one more question, do you or any one have a picture of what exactly Im looking for? Im just a little confused. I was looking at my chiltons and looked at the timing chain section and it sais that in order to get to it I have to take off the head assymbly and it shows a picture of the timing chain and it goes from the crankshaft up to a large gear in the head area and then below it is another picture of the camshaft gears connected my a chain and the caption says time chain installation. And then you told me to check the top timeing chain guard, I thought by that you mean there are two guards and you want me to check the top one. Forgive my ignorance but is there two timing chains? I don't know much about this motor and the timing chain is realy different from what Im used to. Even if you don't have a picture an explination would help emensly.

The reason for asking is because its below freezing this time of year and I dont realy want to stand out there too long trying to figure out whats wrong.

Another thing I havent been driving it lately except for moving it in and out of the drive way so we can get our other cars out, but I noticed that the sound has been quieter lately and just a little bit ago it was just going tik tik tik instead of TAK TAK TAK. I don't know if that changes anything or not, Im sure it wouldn't hurt to check the timing chain tho.

Thank you againAdiosJosh

[Nismochick240]

yes there are 2 timing chains (weird huh?) its a ***** to replace lol

anyways heres a pic of what you would see. the top guard is located right when you take the valve cover off. this may not be your problem but this is what was wrong with mine. When you take the valve cover off you will see it directly ABOVE the timing chain. no need to remove timing chain. its just a guard that may be broken. i've attached a quitly drawn paint picture that may help you out. the gaurd is what you need to look at. if your ka has every had a timing chain replacment it may not even been on there and you must continue your search. lol. anyways, IF THE GUARD IS STILL ON THERE BUT IS NOT BROKEN I RECOMMEND TAKE IT OFF ANYWAYS. NISSAN DISCONTINUED THAT PART DUE TO COMMOM BREAKAGE. Good luck. Let me know if you need anything else okay?

[Nismochick240]

btw, if you cant find out, I recommend taking it to a shop to let them look at it. Then you dont have to freeze out in the cold lol. Most garages wont charge you to take a look at it and figure out the problem. Others may only charge you like 20 bucks. If you were closer to SC I would tell you to take it to my boyfriend's shop. He'd look at it for free and prolly hook you up if something seriously's wrong with it.

Also, watch driving it. If you have another car, I would park it until you figure the problem. I saw you said only back and forth in the driveway. That's ok.

[(Yoshi)]

I must say I am blown away by your artistic talent lol. I apreciate it tho. Its supposed to be 22 F tommorow so hopefully the sun is out and Ill check then. Right now I'm back to the good ole days rocking my moms Dodge Grand Caravan Sport lol. Im going to take a look and take off the guard and see if that helps, if not I was planning on taking it to a local shop and have them go ahead and do a full diagnostic electrical and all. Ill let you know if I need any more help.

Thanks agianAdiosJosh

[(Yoshi)]

Wow its cold out side lol. Ill be, I just checked and I found the guard no problem and I said this must be it and I touched it and the thing just fell off. Its nuts, if that got back into my cams, my motor would be shot. It was practicaly worn right through, luckily my chain didn't break or get torn up. I fired it up and sure enough that was the problem.

Thank you so muchAdiosJosh

[Nismochick240]

did you crank your car up to see if it still knocked. i would hope no metal shaving got into your motor good luck

[(Yoshi)]

Yup, I fired it up and it ran smooth and quiet. Thank you again

AdiosJosh

[tjmhillz]

yea we got some snow here im going to check it mine out and see if the same thang happen to mine hopefully it did. well let everyone know

[Nismochick240]

change your oil too. look inside the oil and make sure there are NO metal shaving inside at all

[(Yoshi)]

@tjm hope fully that is all

@Nismo, well I just changed the oil 50 miles ago after I had my fuel injector problem that happend 100miles after I changed it the first time. So it is reletivly fresh. I may just incase but probly not right away...

[Nismochick240]

yea i would just in case. you never know what could happen in 50 miles

[VinceSez]

dang... 1292 posts hahaha that's a lot i envy you

[Nismochick240]

i dont really care about how many posts i have... it's really not that big of a deal lol

[(Yoshi)]

Yeah I may, but it will be when I can work in prefferably a heated garage lol.

Thanks for your helpAdiosJosh

[s14 2510's]

I just left that upper guide out when I Put 91 cams in my 95. If you read service bulitins on the ka24de in 240sx they were comonly remved to eliminate the timing chain noise.

[tjmhillz]

well i looked closely and my guides are gone but thats not the problem. its my intake rocker arm thats making that tapping noise. i listened to where the noise was coming from and found it out. so that was my problem not my timing chain guide
